Under the GFA Policy, the project proponent- an airport developer or the respective State Government willing to establish a Greenfield airport is required to send a proposal to the Ministry of Civil Aviation  in the prescribed format for 2-stage approval process i.e., 'Site Clearance' followed by 'In-Principle' approval.
Since 2019, 6 Greenfield airports namely, Kalaburagi , Orvakal  , Sindhudurg , Itanagar Kushinagar  and Mopa  have been operationalised, out of which Kushinagar and Mopa airports are International airports.

After deregulation of airline sector, the airfare is market driven and is neither established nor regulated by the Government. Air ticket prices generally vary depending upon the market forces. Airline pricing runs in multiple levels {buckets or Reservation Booking Designator } which are in line with the practice being followed globally. Due to dynamic fare pricing, the tickets bought in advance are much cheaper than those purchased near the date of travel.
The airlines are free to fix reasonable tariffs under the provisions of sub-rule  of Rule 135 of the Aircraft Rules, 1937 having regard to all relevant factors, including cost of operation, characteristics of services, reasonable profit and the generally prevailing tariff.
Directorate General of Civil Aviation  has a Tariff Monitoring Unit that monitors airfares on certain routes on monthly basis to ensure that the airlines do not charge airfares outside a range declared by them. The airlines are compliant to the Sub Rule  of Rule 135 of the Aircraft Rules, 1937 as long as fare charged by them is in line with fare displayed on their website.

Vide the said Circular, airlines are mandated to nominate a protocol officer at the aerodromes to facilitate VIPs during their travel.
